Coefficients when writing cell diagrams

Postby sofiakavanaugh » Thu Mar 15, 2018 12:17 pm

Hi,

When writing cell diagrams, do we need to include the coefficients we assigned when balancing the chemical rxn?

For example if you had Pt(s) | H2(g) | 2H+(aq) || Cl2(g) | 2Cl-(aq) | Pt (s) , do you include the 2 in front of the H+ and the Cl-? Why or why not?

Thanks

We only have to write the species that would take place in the redox reaction - its simply a summary of the cell structure. There is no need to write the coefficients in the cell diagram. However, if you were given a cell diagram and told to write the half reactions, you must balance the equations accordingly.

No. Cell diagrams are simply a summary of the players in the redox reactions.

Coefficients are not in the cell diagram, only the chemical equation
